Uses the UV coordinates generated by the Imposter UV node to sample an specific imposter texture. This creates the illusion of a 3D object on a billboard object because the imposter texture's frame changes based on the camera direction and angle.
Texture - The texture asset to sample. Sampler - The texture sampler to use for sampling the texture. UV0 - The virtual UV for the base frame. UV1 - The virtual UV for the second frame. UV2 - The virtual UV for the third frame. Grid - The current UV grid, which is used to find the corresponding sample frames. Weights - The blending values in between the slected three frames.
RGBA - A vector4 from the sampled texture. RGB - A vector3 from the sampled texture. R - The r channel of the sampled texture. G - The g channel of the sampled texture. B - The b channel of the sampled texture. A - The a channel of the sampled texture.
Sample Type - Select whether to sample three frames or one frame, three frames for smoother result, one frame for better performance.
